I used a plastic Ariel cake topper and just piped on her mermaid tail? (is that what it's called!?)
I was pretty happy with how it turned out...I was sort of dreading having to freehand Ariel, but was so excited when I found I had the topper.
The cupcake cake is made up of 24 marble cake cupcakes and buttercream icing.
Happy Birthday Eilish!
